Granulomatous infectious disease in an immunosuppressed patient: a case report with radiological and pathological correlation.

We report here on a case of disseminated aspergillosis in an immunocompromised patient with Wegener's granulomatosis to illustrate the complexity of brain imaging diagnosis in the presence of concomitant infectious, immunological and ischemic diseases.

Coccidioidal cerebral abscess with peripheral restricted diffusion.

The authors present here a case of a brain abscess with atypical imaging features, including peripheral water-motion restriction. Reduced diffusion at intracavitary projections can be helpful in identifying cases with fungal etiology.
